Background Monozygotic twins are nearly identical in genotype and phenotype because monozygotic twins arise from one fertilized oocyte. In all cases of discordant karyotype in monozygotic twins, trisomy 21 accounts for about one in 385,000.

A core gut microbiome in obese and lean twins
The human distal gut harbours a vast ensemble of microbes (the microbiota) that provide important metabolic capabilities, including the ability to extract energy from otherwise indigestible dietary polysaccharides.

Methylomic analysis of monozygotic twins discordant for childhood psychotic symptoms
Childhood psychotic symptoms are associated with increased rates of schizophrenia, other psychiatric disorders, and suicide attempts in adulthood; thus, elucidating early risk indicators is crucial to target prevention efforts.

Concordant Intestinal Atresia in Two Pairs of Monozygotic Twins
Intestinal atresia in both twins from the same pregnancy is very rare. Only seven pairs of twins have been described. The authors report on two cases of monozygotic twins with different types of intestinal atresia and clinical evolution.

Discordant renal progression of Fabry disease in male monozygotic twins: a case report
Background: Fabry disease (FD) is a rare X-linked lysosomal storage disease caused by mutations in the GLA gene that encodes α-galactosidase A (α-GAL).

Associations between birth size and later height from infancy through adulthood : an individual based pooled analysis of 28 twin cohorts participating in the CODATwins project [PDF]
Background: There is evidence that birth size is positively associated with height in later life, but it remains unclear whether this is explained by genetic factors or the intrauterine environment.

Epigenetics of discordant monozygotic twins: implications for disease
Monozygotic (MZ) twins share nearly all of their genetic variants and many similar environments before and after birth. However, they can also show phenotypic discordance for a wide range of traits.

A Twin Study of Genetic Contributions to Hippocampal Morphology in Schizophrenia
Our goal was to establish whether altered hippocampal morphology represents a trait marker for genetic vulnerability in schizophrenia. We outlined the hippocampi on high-resolution MR images obtained from matched samples of control and discordant ...

Indian twin registry: A gold mine for genetic studies
Twins are a source of curiosity, both for the family and the scientific community. Genetic similarities between twins have been the preferred choice to study the heritability of traits.
